Constructor Detail

LineInterleavedRasterData

public LineInterleavedRasterData(RasterRect sampleDomain,
                                 int rasterWidth,
                                 int rasterHeight,
                                 RasterDataInfo dataInfo)

Creates a new LineInterleavedRasterData with given size, number of bands and data type, backed with no data.

Parameters:

sampleDomain - the raster rectangle defining the sample domain of this raster data.

rasterWidth - width of the underlying raster data.

rasterHeight - height of the underlying raster data.

dataInfo - containing information about the underlying raster.

LineInterleavedRasterData

public LineInterleavedRasterData(RasterRect sampleDomain,
                                 int rasterWidth,
                                 int rasterHeight,
                                 RasterReader reader,
                                 RasterDataInfo dataInfo)

Creates a new LineInterleavedRasterData with given size, number of bands and data type

Parameters:

sampleDomain - the raster rectangle defining the sample domain of this raster data.

rasterWidth - width of the underlying raster data.

rasterHeight - height of the underlying raster data.

reader - to be used for reading the data, may be null

dataInfo - containing information about the underlying raster.

Method Detail
